Plz help me and my lil sis suck at sience :P
Answer:
It is translucent
Explanation: i put it and got it right
Electromagnetic waves travel at in vacuum
The fundamental properties that can be attributed to waves are;
Other properties are ;
Electromagnetic radiation can be regarded as radiation that has waves of the electromagnetic field, which propagate through the space, and it moves along with electromagnetic radiant energy.
Therefore, electromagnetic waves travel at 300,000,000 metres per second in vacuum.
(1 Point)
4 m/s2
2.5 m/s2
1.5 m/s2
1 m/s2
Answer:
1.5
Explanation:
resultant force=8-5=3N
using f=ma
a=f/m
=3/2
=1.5
Why is gravity an example of scientific law?
Because it is a basic concept that defines a constant and universal behaviour of nature, gravity is seen as an illustration of a scientific law.
Scientific laws are succinct formulations that precisely explain a natural occurrence and are the result of in-depth observation and investigation. Einstein's theory of general relativity or Newton's law of universal gravitation both use the concept of gravity to explain how mass-containing objects interact with one another in space.
It offers a mathematical framework that enables researchers to perform precise projections and estimates about celestial body motion, the behaviour of things close to the surface of the Earth, and the structure of the cosmos.
The fact that gravity is recognised as a scientific rule is a reflection of the fact that it is widely accepted and has been shown to have practical applications.
